Smlight - Zigbee and Matter Thread USB Ethernet POE Adapter SLZB-MR1U

Smlight SLZB-MR1U: Modular Zigbee, Thread & USB-over-Ethernet Adapter

The SMLIGHT SLZB-MR1U is a cutting-edge USB and Ethernet Zigbee adapter designed for advanced home automation setups. Built on the solid foundation of the SLZB-MR1, this upgraded model introduces a powerful USB passthrough-over-Ethernet feature, enabling remote use of USB dongles (Z-Wave, BLE, Matter, RF, etc.) across your network.

Equipped with dual chipsets—Texas Instruments CC2652P7 and Silicon Labs EFR32MG21—the MR1U delivers native support for Zigbee 3.0 and Thread (Matter-over-Thread), while remaining fully modular and extendable via USB. Pre-flashed with SLZB-OS, it provides seamless compatibility with popular platforms like Zigbee2MQTT, ZHA, OpenThread, and Z-Wave JS.
